Gambling is a fantastically, astonishingly lucrative market, yet online gambling is more or less illegal in the United States, despite the popularity of physical casinos in Vegas and Reno and Atlantic City.

Few industries are this regulated: Donald Trump himself couldn’t get a gambling license in Las Vegas last year.
